How does a flylight work?
Flylights utilize ultraviolet bulbs to attract flying insects into the product, before either zapping them dead on a high voltage killing grid or trapping them on a sticky glueboard. UV bulbs attract flying insects by emitting a wavelength of light attractive to flies. Flying insects are attracted to the bulb which emits UV at a level comparable to that of the sun, which the flying insect has a natural attraction to as a source of heat.
.How often should I change my bulbs and why?
We recommend that UV bulbs are changed every 12 months to ensure maximum efficacy. The levels of UV produced by fluorescent bulbs deteriorates rapidly throughout the life of the bulb. Whilst the bulb will continue to glow blue or green indefinitely, after approximately 8,000 hours the amount of useful UV (Which humans cannot see) drops to a level where it is no longer attractive to flying insects. As a result, UV bulbs must be replaced annually to ensure they remain effective in producing useful levels of UV. This replacement cycle is typically undertaken just before the peak insect season, (March/April within North America) to ensure the flylight is producing the maximum amount of UV throughout the critical insect season.
